Assembling a computer Assembling a computer Presentation Transcript

  • Presentation onAssembling a ComputerPresenting By:Neeraj Dhiman
  • Safety Procedures Clean work area free of dust and food Never open a monitor Remove jewelry and watches Turn power off and remove power plug Fire extinguisher available Use anti static mat and wrist strap Hold cards by edges/avoid touching chips Put components on non conductive surface Do not use magnetized screw drivers
  • Electrostatic Discharge If you notice it, it’s at least 2000 volts Charge of 200 volts can damage components Keep all components in anti-static bags Humidity above 50% Use grounded mats (workbench and floor) Use wrist straps Periodically touch unpainted grounded metalcomputer parts to lower the body’s staticenergy
  • Keeping an Inventory Document all components, parts purchased Use an inventory checklist May be difficult to recall later Will be helpful in locating and downloadingdevice drivers Note specific warranty info Save specifics about installation andmaintenance requirements so warranties will bevalid Use small box to hold all manuals and disks Label box for specific computer Store in secure place
  • Choosing a computer case andsystem unit Case Allows easy access tointernal components Provides room for expansion ATX form factor Available desk top space LED indicators on front Dust filters if area wherecomputer to be used is dusty Power supply Minimum 250watts ATX Single 20 pin Fan pulls airthrough casefrom front toback
  • Preparing to installMotherboard Review the motherboard location map Configure the motherboard Install the CPU, heat sink and fan, RAM Connect power supply cables tomotherboard power connectors and misc.connectors to correct switches and lights Set the system BIOS
  • Configuring the processor Set jumper settingsfor appropriatefrequency Ensure the CPUused supports theBUS speed and theCPU clock speed ofMotherboard
  • Installing the CPU ZIF (Zero Insertion Force) trait on nearly all socket 7 andsimilar types Inspect pins for damage Locate pin 1 on both chip and socket Open the ZIF socket (raise lever) Insert processor (should easily slide on) Make sure there is not a gap between bottom of chip andsocket Push lever down Set CPU voltage jumper settings if necessary (Pentium IIand later CPU’s adjust automatically to voltage)
  • Install Heat Sink and Fan Attach fan to heat sink if not alreadyattached Apply thin layer of compound to chipsurface Attach heat sink by placing squarelyon top of processor and press downgently Bend clips in place to hold sink Make sure there is good contactbetween sink and Chip surface Wipe off any excess compound Plug power cord from fan to fanpower pins on motherboard
  • Install RAM Two types RAM used onmost PC’s DDR1 DDR2 Look at motherboard map todetermine which bank toplace DIMM 1 module in Orient the Dimm chip overthe slot (keyed) and insertinto slot Lock in place by closinglevers
  • Installing the Motherboard Position case for easy access, locate holes onmotherboard and corresponding holes on case Insert spacers that came with motherboard intoholes on case and install plastic standoffs into holeson motherboard Carefully slide the board into the case, lining upholes Tighten board to case with screws Verify that the back of the motherboard is nottouching the case, all slots and connectors line upproperly, board is securely held in place, and boarddoes not bend when pressed
  • Attaching LEDs, key lock andspeaker Use motherboard manual as a guide forproper placement Turbo LED (mainly legacy item) Power LED Hard drive activity LED Key lock switch (common with oldersystems, rare now; prevented BIOSmeddling) PC speaker
  • Connect power supply cables AT motherboard Locate two large wire leads from power supply(P8 and P9) Locate 12 pin power connector on motherboard Plug P8 and P9 into connector Be sure black wires are in the middle beside oneanother ATX motherboard Attach the connector that is keyed to fit only oneway into the motherboard connector
  • Attach hard drive and CD-ROM Use separate IDE cables if possible and set both jumpers toMaster (or single on the hard drive if available) If sharing an IDE cable, set the hard drive to Master and the CD-ROM to slave Install hard drive away from power supply which can act like amagnet and destroy data Keep hard drive near front of case to benefit from air drawn intocase and keep away from other hardware Slide drive into selected drive rail and screw drive into place Attach ribbon cable to the primary controller of the motherboardand attach power cord Follow with CD-ROM installation and attach to secondarycontroller of the motherboard
  • Installing a video card Use AGP expansion slot ifavailable, otherwise use PCI or ISA Remove slot insert and insertvideo card by aligning pins andgently applying pressure Secure to case with a screw Some motherboards have built-invideo. If you want to install anexternal card then you mustdisable the built in video in theCMOSAGP VIDEO CARD
  • Post Assembly Checklist All expansion cards are fully inserted CPU fan is attached to power The 110/220 volt switch is configured properly Drives are connected to power Ribbon cables are attached correctly Fans are free from interference from wires CPU voltage settings are correctly configured Power switch is off and power supply connectors areconnected properly to motherboard All connections are tight Pins are properly aligned Close the case before booting Connect keyboard, mouse and monitor and plug in AC power
